Flight delays cost passengers $16.7B

That's the price a study delivered Monday to the Federal Aviation Administration puts on the cost to passengers for flight delays in 2007. That was the latest year for which complete data was available.

The cost to airlines for delays was $8.3 billion, mostly for crew, fuel and maintenance.

Overall, the cost was $33 billion, including to other parts of the economy.

The things the researchers looked at included passengers' lost time waiting for flights and then scrambling to make other arrangements when flights are canceled.
